5.1 Formation

Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.

Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.

More about Mylonite and Anorthosite

Here you can know more about Mylonite and Anorthosite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mylonite and Anorthosite consists of mineral content and compound content. The mineral content of Mylonite includes Porphyroblasts and mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Mylonite vs Anorthosite, the texture, color and appearance plays an important role in determining the type of rock. Mylonite is available in black to grey colors whereas, Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors. Appearance of Mylonite is Dull, Banded and Foilated and that of Anorthosite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Mylonite vs Anorthosite. The hardness of Mylonite is 3-4 and that of Anorthosite is 5-6. The types of Mylonite are Blastomylonites, Ultramylonites and Phyllonites whereas types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mylonite and Anorthosite is white. The specific heat capacity of Mylonite is 1.50 kJ/Kg K and that of Anorthosite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Mylonite is heat resistant, impact resistant, pressure resistant whereas Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant.
